即时操纵安全钳的电梯抗坠落安全保护机构
首发时间:2009-07-06
摘要:电梯抗坠落安全保护装置是在电梯因各种原因发生坠落时将轿厢制停在导轨上的装置,对于电梯安全保护非常重要。本文在分析限速器、安全钳工作原理的基础上,提出了一种可以即时操纵安全钳的机构。在电梯坠落时,主机构即时操纵安全钳制停轿厢,附加子机构推出安全销吸收部分下坠能量。安全钳在较低的下坠速度下工作,对于轿厢、乘客、导轨的危害较小。

Anti-falling safety mechanism of elevator with controlling safety gear immediately
Abstract:Anti-falling elevator safety protection device can stop the car on the rail when the elevator fall occurred by various reasons. This device is very important for the safety of elevator. Based on the analysis of speed governor and safety gear, a new mechanism is proposed to operate safety gear. As the time of elevator fall, the main mechanism control safety gear to stop car and the odditional sub-mechanism push out safety pin to absorb a part of falling energy. As the safety gear working at a low speed, the harm to passenger, car and orbit are little.
Keywords: mechanical design and principle safety protection device elevator
